The Carter Family, Roy Acuff and Bill Monroe, among others, helped pave the way for generations of country artists. Pioneers 2 spotlights these trail blazers along with a pair of Texans, honky-tonk king Ernest Tubb and singing cowboy sensation Tex Ritter. Chet Atkins (Alabama Jubilee) and Earl Scruggs (Polka on a Banjo) add some hot pickin’, while comedians Lonzo & Oscar in Country Music Time commemorate the influential folks who made the Opry great.
